Title: Système d'appariement pour la reconnaissance rapide de locuteur
Inventor: MOURAD RAJI
IPC: G10L17/00
Filed: 2015-12-29
Abstract: La majorité des systèmes de reconnaissance de locuteur sont basés sur le calcul de la distance ou la probabilité entre de vecteurs caractéristiques d'un locuteur inconnu et les modèles enregistrés dans la base de données du système. Le processus d'identification dépend du nombre de ces vecteurs caractéristiques, leurs dimensions et le nombre de locuteur à identifier. L'idée de cet algorithme est de développer un système capable d'identifier une personne en utilisant un échantillon de sa parole. Nous avons choisi de travailler avec les systèmes dépendant du mot prononcé (word-dependent system) en utilisant par exemple le mot correspondant au chiffre « one» en anglais comme mot de passe. En effet, le système identifie les locuteurs même s'ils prononcent le même mot de passe, en d'autres termes, nous cherchons à trouver la signature vocale de chaque personne dans la prononciation du mot « one ». Les caractéristiques du signal vocal sont extraites en utilisant l'estimation de la densité spectrale de puissance, et la reconnaissance est faite à l'aide de l'algorithme de raji (journal of computational chemistry, 1997) basé sur le calcul de la distance eosine par rapport à une interpolation cubique des signaux constituant la base de données.

Title: Method of electroplating corrosion resistant coating
IPC: C25D5/14
Filed: 1967-10-25
Abstract: A duplex Ni plate is prepared on a basis metal, e.g. Fe, Cu, Ni, Zn, or alloys thereof including steel or brass, to receive a Cr plate, by first electro-depositing on to the basis metal a S-containing bright Ni plate, and then electro-depositing to a thickness of at least 0À6 micron (e.g. 0À6-3 microns) an outer micro-cracked Ni plate from an aqueous bath containing 120-187 g/l Ni++, 110- 225 g/l NiCl 2 .6H 2 O and 150-900 g/l Ni (BF 4 ) 2 . For Zn die castings, a base Cu plate e.g. 7À5-15 micron thick is preferably electro-deposited, e.g. from a plating bath containing 45-60 g/l Cu (as Cu CN) and 15-22 g/l free NaCN or KCN, prior to Ni plating. Prior to the first electro-deposition, a preliminary S-free semi-bright Ni plate may be electro-deposited from a conventional Watts, sulphamate, fluoborate or chloride-free bath containing 0.2-3 g/l of a semi-bright additive, such as coumarin, (diethoxylated) butyne diol, chloral or bromal hydrate, formaldehyde or piperonal, to a thickness of 5-40 microns. The bright Ni plate may be electro-deposited from similar baths containing nickel sulphate, chloride with or without fluoborate or sulphamate, or boric acid, and a primary and secondary brighteners, to a thickness of 7-12 microns. Examples of primary brighteners, e.g. in amount of 0À002-0À2 g/l, are (diethoxylated) butyne diol, phenyl propiolamide, propargyl alcohol, 3-butyne 1-ol, 2-methyl-3- butyne-2-ol, and [alpha], a'bis (pyridinium iodide) 2, 6-lutidine. Secondary brightners, e.g. in amount of 1-30 g/l, include saccharin, Na benzene monosulphonate, Na vinyl sulphonate and Na metabenzene disulphonate secondary auxiliary brighteners, e.g. in amount of 0À5-3 g/l, include Na allyl suphonate and Na 3-chloro butene 1-suphonate. The plating bath for electro-depositing the outer micro-cracked Ni plate preferably further contains 0À002-0À4 g/l primary brightener and 0À1-1 g/l secondary brightener, as above, and 0À1-0À8 g/l an additive heterocyclic having at least 2 N atoms in the ring structure, preferably hexamethylene tetramine, piperazine, pyrazine, 2, 6-dimethyl pyrazine, or 1:11 ethylene 2:21 dipyridinium dichloride other examples are specified. The final Cr plate may be electro-deposited on the bright Ni plate from a bath containing CrO 3 and SO 4 -(added as Na 2 SO 4 or H 2 SO 4 ), with or without SrCl 2 or SrSO 4 or K 2 SiF 6 , to a thickness of 0À1-1 micron.
Patent ES-349773-A1 (ES)
Title: Method of making voltage regulators
IPC: H02J7/24
Filed: 1968-01-13
Abstract: A regulator for use with an alternator on a road vehicle provides power through a full wave rectifier to a battery having a positive terminal 12 and a negative terminal connected to an earthed line 13, the alternator also supplying power through one or more auxiliary diodes to a positive supply line 11. When the battery voltage is below a predetermined value, a Zener diode is non- c6nductive and so no base current flows through a transistor 19. Current flowing through a resistor 21 turns on a transistor 22 and current flows in the field winding 23. When the predetermined voltage is reached, the Zener diode 17 conducts to provide base current to the transistor 19, which removes the base current from the transistor 22. By means of the feedback connection through resistor 25 and capacitor 26 the circuit oscillates with transistors 19, 22 alternately conductive, the mark-space ratio being determined by the current flowing through the Zener diode 17, which in turn is determined by the battery voltage. The arrangement is such that the mean current flow in the winding 23 maintains the battery voltage substantially constant. The method of manufacturing the regulator is described, Figs. 2 and 3 (not shown).
Patent ES-355631-A1 (ES)
Title: Improvements in or relating to the production of polyurethane foam
IPC: B29C44/28
Filed: 1968-06-28
Abstract: Polymeric foam is continuously cast on a conveyer and the sides of the foam are restrained by a lining which moves and rises with the foam so that the top surface of the foam, after setting, is substantially flat. The lining surfaces move over side surfaces and are stretched longitudinally in the area where the foam rises so that there is no substantial relative movement between the top of the foam and the lining surface. The lining surface 96 is stretched between idler rolls 11 and pinch rolls 12, the idler rolls comprising two non-parallel rollers around which the sheet runs, the rollers being rotatable about the vertical to increase the stretching and the angle of rise of the sheet. The positions of the rolls 11, 12 are longitudinally adjustable.
Patent ES-361117-A1 (ES)
Title: Bidirectional electronically scanned antenna system
IPC: H01Q25/00
Filed: 1968-12-05
Abstract: Beams are formed on each side of an electronically scanned lens by feed system means energizing sets of radiating elements which are disposed on each face of the lens, and which are connected by an array of phase shifters. As described, an aerial system includes a transmission type lens 2, Fig. 3, having large numbers of radiating elements 4, 5 on opposite faces 6, 7, pairs of said elements being connected together through reciprocal or non-reciprocal type phase shifters 3. A horn 8 feeds the elements 5, so that a beam 10 is radiated by the elements 4. Similarly, a horn 9 feeds the elements 4, so that a beam 11 is radiated by the elements 5. Drivers 14 controlled by a computer 15 adjust the settings of the phase shifters 3, and the spherical wave fronts from the horns 8, 9 are converted to provide steerable radiated phase fronts which may be planar or, for specially shaped beams, non-planar. A transmitter 16 and a receiver 17 are coupled through a duplexer 18. The horns 8, 9, Fig. 5, may be off-set to reduce aperture blocking. Two systems may be provided which are placed one above the other and at right angles, so that 360 degrees azimuthal coverage is obtained although each side of each lens scans over only 45 degrees. In another embodiment the feed horns (208), (209), Fig. 7 (not shown), are polarized, and polarized reflectors (219), (220) are provided on the faces of the lens, each of which reflects the phase front from the opposite horn but passes that from the adjacent horn. Thus, beams (210), (211) are formed on the same sides of the lens as their generating feed horns (208), (209). Reciprocal type phase shifters (203) must be used.
